International Journal of Science, Environment ISSN 2278-3687 (O) and Technology, Vol. 6, No 4, 2017, 2445 – 2449 2277-663X (P) Anthology GREGOR JOHANN MENDEL (1822–1884): A MAN WHO LIVES AFTER DEATH K. Jagadeesan Assistant Professor Department of Animal Genetics and Breeding, Veterinary College and Research Institute, Orathanadu 614 625 E-mail: [email protected] Abstract: In this article the life of Gregor Johann Mendel, Father of Genetics is reviewed. The aim is to bring the reader’s attention to the hardship which he faced throughout his life journey. Further, the author humbly pays homage through a verse about the life of Gregor J. Mendel. Keywords: Gregor Johann Mendel, Genetics, Life history. Every one of us know the meaning and usage of the very old phrase “like begets like” – simply it means, human (re)produce human; monkey (re)produce monkey; tiger (re)produce tiger, plant (re)produce plant so on so forth. Though, superficially the above sentences look unquestionable, the degree of similarity between parents and their offspring is debatable. In today’s scientific world, we know the exact reasons for similarity / dissimilarity among individuals in a lineage but, during 19th century it was not the scenario. Then, the science of ‘inheritance’ was very much primitive and Darwin’s pangenesis theory was widely existed and discussed. In this backdrop, a poor humble but studious monk called Gregor Johann Mendel put forth the ‘laws of inheritance’ with the strong mathematical evidences observed in his numerous experiments across generations in garden pea plants (Paisum sativum). Unfortunately, it did not get due attention and appreciation by the scientific community. -
Gregor Johann Mendel
Title: It Doesn’t Take a Rocket Scientist: Great Amateurs of Science Author: John Malone ISBN: 0-471-41431-X chapter 1 Gregor Johann Mendel The Father of Genetics It is 1854. In the low hills just outside the Moravian capital, Brüun, there is a monastery with whitewashed brick walls sur- rounding gardens, courtyards, and buildings that are chilly even in summer. The fortresslike walls were built to protect its origi- nal inhabitants, Cistercian nuns, who took up residence in 1322. The nuns departed late in the eighteenth century, and the mona- stery lay empty for a while, falling into disrepair. It was taken over by a community of Augustinian monks in 1793—they had been displaced from the ornate building they occupied in the center of Brüun because Emperor Franz Josef of the Austro- Hungarian Empire wanted their jewel of a building for his own residence and offices. By 1854, the monastery of St. Thomas had been headed by Abbot Cyrill Napp for several years. Within the Catholic Church, the Augustinian order had a reputation for liberalism, and Abbot Napp was particularly forward-looking. Born into a wealthy local family, he had very good connections with the leaders of secular society in Moravia, which were useful when the more conserva- tive local bishop objected to the extent of the research taking place at the monastery. Since 1827, Napp had even been presi- dent of the prestigious Royal and Imperial Moravian Society for 5 6 It Doesn’t Take a Rocket Scientist the Improvement of Agriculture, Natural Science and Knowl- edge of the Country (popularly, the Agriculture Society), which had been founded in 1807, the same year that Emperor Franz I had decreed that the monks of St. -

He was the son of Anton and Rosine Mendel, and had one elder and also a younger sister. During his childhood, Mendel worked as a gardener, studied beekee ping, and as a young man attended the Philosophical Institute in Olomouc. Upon recommendation of his physics teacher Friedrich Franz, he entered the Augustinian Abbey of St. Thoma s in Brno in 1843. Born Johann Mendel , he took the name Gregor upon entering monastic life. In 1851 he was sent to the University of Vienna to study, returning to his abbey in 1853 a s a teacher, principally of physics. Mendel’s Impor tance Gregor Mendel, who is known as the "father of modern genetics", was inspired by both his professors at university and his colleagues at the monastery to study variation in plants, and he conducted his study in the monastery's garden. Between 1856 and 1863 Mendel cultivated and tested some 29,000 pea plants (i.e. Pisum sativum). This study showed that one in four pea plants had purebred recessive alleles, two out of four were hybrid and one out of four were purebred dominant. His experiments brought forth two generalizations, which later became known as Mendel's Laws of Inheritance. -

The university consisted of several colleges but since the second half of 19th century one after another was closed until finally no one was left with exception of the Faculty of Theology. After the World War II the University of Olomouc has been reestablished under the name Palacky University. There are now four faculties — Medicine, Natural Sciences, Philosophy and Pedagogy. 1.

Gregor Mendel and the Foundation of Genetics
Journal of the History of Biology (2005) 38: 239–272 Ó Springer 2005 DOI 10.1007/s10739-004-5427-9 Scientific Breeding in Central Europe during the Early Nineteenth Century: Background to Mendel’s Later Work ROGER J. WOOD Faculty of Life Sciences Manchester University Stopford Building- 3.614 Manchester M13 9PT United Kingdom E-mail: [email protected] VITEˇ ZSLAV OREL Barvicˇova 51 60200 Brno Czech Republic E-mail: [email protected] Abstract. Efforts to bring science into early 19th century breeding practices in Central Europe, organised from Brno, the Hapsburg city in which Mendel would later turn breeding experiments into a body of timeless theory, are here considered as a signifi- cant prelude to the great discovery. During those years prior to Mendel’s arrival in Brno, enlightened breeders were seeking ways to regulate the process of heredity, which they viewed as a force to be controlled. Many were specialising in sheep breeding for the benefit of the local wool industry while others were showing an interest in commercial plants, especially fruit trees and vines, and later cereals. Breeders explained their problems in regulating heredity in terms of (1) climatic influences (2) disruption due to crossing (3) sports or saltations. Practical experience led them to the concepts of ‘inheritance capacity’ and the ‘mutual elective affinity’ of parents. The former was seen to differ among individuals and also among traits; the latter was proposed as a means of adding strength to heredity. The breeders came to recognise that traits might be hidden and yet transmitted as a ‘potential’ to future generations.
